In round numbers, you can literally crank out about 100W for about 10 hours per day, so a good day's labor is 1 kiloWatt*hour (kWh), and you'd have to pay about $100 in wages for the crank-turner. (That seems to me like a reasonable amount of energy to expect from a home-size wind turbine, too.) From the grid, we currently pay about $0.15 (fifteen cents!) for that much energy.

An "AA" alkaline battery, for which we pay $0.50-$1.00, is good for about 1 Watt*hour (or at least $500/kWh).

My "5 kW" solar array, on a sunny day in December, is putting out about 10 kWh ($1.50), but put out a little more than 30 kWh ($4.50) on a sunny day in June. (Installed cost, with no energy storage, was about $15,000 in 2014, before subsidy incentives.)
